Signal Inputs
Once you have connected a signal source to the rear panel of your instrument, there are several menus you will want to use to set up your signal:
Config > Input Mode: select whether the input mode is single or simultaneous input and to enable or disable SyncVu.
Config > SDI Input: select how SDI inputs are displayed. The instrument can automatically detect the input format, sample structure, and transport type
(or specify these manually). You can also choose to not display the EAV,
SAV, and ANC data; set chroma alignment; select HD colorimetry; and set the dual link threshold.
Config > Composite Input: select the input type, set sync AFC speed to fast or slow, set DC restore to off, slow, or fast, set NTSC setup on or off, and set
PAL vector to normal or +V (requires Option CPS).
Input 1A/1B and Input 2A/2B: select to view the complete signal or selected streams of a 2xHD 3 Gb/s SDI signal. Input selections that appear depend on installed options and display settings. Possible menu options include Input
1A, 1A.1, 1A.2, 1A.1+2, 1B, 1B.1, 1B.2, and 1B.1+2
If you have two separate signals connected to two different inputs on the rear panel of the instrument, you can control which channel is displayed by pressing the associated input button on the front panel of the instrument.
When the input button is lit, the channel is displayed. When the button is not lit, that channel will not be displayed.
SDI Signals
Connect one or more 3G-SDI, HD-SDI, or SD-SDI signals to the SDI inputs on the rear panel of the instrument. After that is finished, use the front panel buttons to set the parameters for monitoring the signals, such as thresholds, alarms
monitored, and audio source. (See Figure 9.) (See Figure 10.) (See Figure 11.)
NOTE.
You can connect up to four SDI signals to an instrument with Option 2SDI.
This option allows you to add a second SDI module into Slot 2 of the instrument rear panel.

Composite Signals
Connect a composite signal to one of the CMPST inputs on the rear panel of the instrument. You must terminate the loop-through for this input. After that is finished, use the front panel buttons to set the parameters for monitoring that signal.
The composite inputs are passive and require external termination.
If this instrument is installed to monitor an operating link, the destination receiver and the connecting cable serve as the termination. This monitoring connection checks the performance of the entire path. The return loss of the instrument is sufficiently high that, in most cases, the destination receiver sets the system return loss.
WVR7200 Waveform Rasterizers User Manual 25
Signal Inputs
In cases where this instrument is placed at the end of a link, a BNC termination must be installed on one side of the loop-through composite connector. The termination must be 75 Ω and DC coupled.
Figure 12: Composite signal connection
Dual Link Signals
The inputs for dual link signals are the same as for SDI signals. Dual Link monitoring allows you to set up your instrument to monitor higher resolution signals than can be monitored using the traditional single link input. Dual link signals are combined in the instrument and then shown as a single signal on a
waveform or other display. (See Figure 13.)
26
Figure 13: Dual Link signal connection
WVR7200 Waveform Rasterizers User Manual
Signal Inputs
When you set input formats, sample structure, and transport type to Auto in the
CONFIG > SDI Input menu, your instrument automatically configures for
Dual Link signals if SMPTE352M (VPID) is present. If SMPTE352M (VPID) is not present, you must manually set up sample structure and transport. View the Video Session Display (STATUS>Display Type>Video Session) to verify proper configuration.
Your instrument automatically detects the format on signals with SMPTE352M
(VPID) while operating on Dual Link signals. You can then view combined Link
A, Link B, and Alpha Channel information, which can help with the identification of correct content. Alpha Channel information is visible, if present. The following
illustration is an example of how the signal components would appear. (See
Figure 14: Dual Link information placement in waveform display
Multi-Input Display Mode
The Multi-Input display mode supports the simultaneous display of up to four
SDI inputs of the same format. You can choose to view a specific stream of a multi-stream signal (such as a 2xHD Level B 3 Gb/s signal) or both streams together. This mode is only available for use in the WFM, GAMUT, and
VECTOR displays.
To Turn On the Multi-Input
Display
Enabling the Multi-Input display mode is a two step process. The Multi-Input menu option is only available in the WFM, GAMUT, and VECTOR pop-up menus when the feature is enabled from the MAIN button menu. To enable this feature:
1. Press and hold the MAIN button.
2. Navigate to Multi-Input Mode.
3. Press the SEL button to highlight Enable.
4. Press the MAIN button to dismiss the menu.
WVR7200 Waveform Rasterizers User Manual 27
Signal Inputs
The Multi-Input display mode is now enabled. The next step is to turn on the feature in a given trace by doing the following:
1. Press and hold the WFM, VECTOR, or GAMUT button to get a display in a tile and to view the pop-up menu for that display.
2. From the pop-up menu, select On for Multi-Input.
3. Press the FULL button to activate the full screen view of that display.
The Multi-Input display mode will now be active.
NOTE.
The Multi-Input display may be selected for each tile individually, but it will only be active when the tile is displayed full screen.
You can configure another tile without multi-input mode so that you can switch quickly between Multi-Input and normal input modes by switching tiles. In four-tile display mode, all tiles will display the currently selected input.
To Select Inputs to View
If you have two separate signals connected to two different inputs on the rear panel of the instruments, you can control which channel is displayed by pressing the associated Input button on the front panel of the instrument. When the input button is lit, the channel is displayed. When the button is not lit, that channel will not be displayed.
Selecting an input to be displayed does not change the inputs being monitored. For example, if you have two SDI signals connected, one to input 1A and the other to input 1B, pressing the 1B button so that it is not lit will eliminate the channel from a trace display, but not stop the channel from being monitored for status or alarms.
To Select Streams to View
You can select to view one or both streams simultaneously of a 2xHD Level B 3
Gb/s SDI signal from an input button pop-up menu. When you press and hold an input button, the pop-up menu that appears allows you to select to view stream 1, stream 2, or both streams of that signal.
The following Input 1A button pop-up menu options appear when a trace display is set to Multi-Input display mode in full screen. If your instrument is equipped with option 2SDI, pressing the 1B, 2A, or 2B input buttons will give you the same menu options as follows, but with different labels.
NOTE.
You can customize the input labels. (See page 29, To Customize Input

Signal Inputs
Input 1A: shows the entire stream when a signal stream signal is used or both streams overlayed when a 2xHD Level B 3 Gb/s signal is used.
Input 1A.1: shows only the first stream of the two streams of a 2xHD Level
B 3 Gb/s signal in the input in the trace display.
Input 1A.2: shows only the second stream of the two streams of a 2xHD
Level B 3 Gb/s signal in the input in the trace display.
Input 1A.1+2: shows both of the two streams of a 2xHD Level B 3 Gb/s signal individually. Each trace is labeled in the display as either Input 1A.1
or Input 1A.2 (or a label you have customized) and shows both streams individually in the trace display.
NOTE.
When Multi-Input mode is disabled, only the first three options in the previous list appear in the input button pop-up menu.
You may select up to eight channels of video from 2xHD video sources, but only the first four are displayed in Multi-Input mode. 2xHD video formats may be used for 3D video content in which the left eye view is typically carried in channel 1 and the right eye in channel 2. The 2xHD formats are defined by SMPTE 425 as an option for 3 Gb/s Level B SDI video. 2xHD formats are available in 720p,
1080i, and 1080p (23.98 - 30 fps).

Signal Inputs
Simultaneous Input Monitoring
Your instrument can monitor two separate signals simultaneously. In this mode, the instrument display is divided into two sides, each with two tiles per input.
This allows you to conveniently view measurement and status displays from two signals at the same time. You can monitor the following combinations:
SDI + SDI, SDI + CMPST.
Connect signals for simultaneous monitoring the same way you would for
connecting two SDI signals or one SDI and one Composite signal. (See Figure 10 on page 24.)
SyncVu™
The SyncVu™ feature works with the simultaneous input monitoring (SIM) mode and allows you to configure the settings for two inputs at the same time. To set the instrument to SyncVu™ mode once you are in SIM mode, do the following:
1. Press the MAIN button.
2. Select SyncVu.
3. Select Enable.
How to Change Settings
Using SyncVu
This instrument can display four tiles. When you are viewing two inputs simultaneously in SIM mode, the tiles on the left side of the display show the first input. The tiles on the right side of the display show the second input. The display type in tile 1 for the first input is the same display type shown for the second input in tile 2: Top left to top right and bottom left to bottom right. SyncVu™ allows you to change the settings for the two related tiles at the same time.
For example, if you have a waveform display in tile 1 of input 1A, then tile 2 is the waveform display for the second input. When you adjust the settings for the waveform displayed in tile 1, the settings for the waveform displayed in tile 2 are adjusted simultaneously. Similarly, adjusting settings for tile 2 are applied to tile 1.
Reference Loop
Reference signals can be Black Burst or Tri-level sync. After you connect the appropriate reference signal, press the EXT REF button the on the front panel of the instrument. You can also choose which format to lock to by pressing the
CONFIG button and selecting External Ref. The default setting is Auto.
The reference input is passive and requires external termination. If you install this instrument to monitor an operating link, the destination receiver and the connecting cable serve as the termination. This monitoring connection checks the performance of the entire path. The return loss of the instrument is sufficiently high that, in most cases, the destination receiver sets the system return loss.
30 WVR7200 Waveform Rasterizers User Manual
Signal Inputs
In cases where this instrument is placed at the end of a link, you must install a
BNC termination on one side of the loop-through external reference connector.
The termination must be 75 Ω and DC coupled. (See Figure 16.)

Waveform Pop-up menu and settings
The Waveform pop-up menu enables you to choose the display style and display mode used in the active tile (SDI inputs only), select a filter to apply to the input signal, to turn on the Multi-Input display mode, and to center the waveform in the display.
To choose a display mode, select from the following the choices (only available while displaying SDI inputs) in the menu:
YPbPr - Displays the input as Luma (Y) and color difference (Pb, Pr) components.
YRGB - Displays the input as Luma (Y), Red (R), Green (G), and Blue (B) components.
RGB - Displays the input as Red (R), Green (G), and Blue (B) components.
SDI > Composite - Displays the SDI input as if it is encoded into composite.
The sync and burst in this mode are synthetic and convey no information about signal quality.
When viewing 525-line SDI input as a composite waveform while using line select mode, both burst phases may appear when you would expect to see only one. This is because the line selection in SDI Mode is an odd/even selection, and composite signals are normally viewed with a one-of-four or one-of-eight line selection.
To choose how the signal components are displayed in the active tile, use the
Display Style menu setting (SDI inputs only) to select:
Parade style - has all the components shown one beside the other.
Overlay style - has all the components drawn at the same location so that they appear one on top of the other.
The Waveform pop-up menu Filter selection allows you to select filters to be applied to the video. This is useful for isolating a specific characteristic of the input. For example, to measure amplitude, you may want to use a Luma or Low pass filter to remove the high frequency components.
To choose a filter select one of the following filters from the Waveform menu:
Flat - Display with the full available bandwidth.
Luma or Low Pass - Display only the low-frequency part of the signal.
Chroma - Display only the part of the signal with frequencies near the color sub-carrier. For Composite inputs only.
Flat + Luma - A combination of a Flat and a Luma waveform from a
Composite input; it shows two waveforms in parade configuration.
NOTE.
For SDI displays, such as RGB mode, the available filters are Flat and
Low Pass. For Composite displays, the available filters are Flat, Luma, Chroma, and Flat+Luma.

Rear Panel is the default setting, where offset is shown as zero when the input and reference are at the same timing at the rear panel of the instrument. If you select Saved Offset, you can save the timing from one signal, and then display the timing relative to that saved offset.
Measure Pop-up Menu
The Measure pop-up menu enables you to save a timing setting for comparison with another signal and specify the zero point of the timing display.
To save the timing of the current input as an offset to the timing display, use the
Save Offset menu entry. The current timing becomes the zero point for the saved offset mode of the timing display. This applies to both the cross-hair target in the middle of the display and the numeric readouts.
NOTE.
You cannot save the timing offset if either the input or reference is missing or unlocked. You also cannot save a reference when in internal mode. Saving an offset in these conditions would lead to misleading results so it is not allowed by the instrument. A warning message appears on the screen if you attempt to save the offset when it is not allowed.
Save Offset allows you to measure the timing between inputs or to match multiple signals. To select the definition for the zero timing offset, use the Relative To: menu entry to select one of the following:
Rear Panel, which means the timing offset is shown as zero when the two signals are timed down at the rear of the instrument.
Saved Offset, which means that the timing is shown as zero offset when the input signal matches the timing of the signal that was present when the offset was saved using the Save Offset menu entry.
This selection changes both the numeric readouts and the target in the middle of the timing display.

Timing Displays for Simple
Versus Complex Timing
The number of circles, with each representing a time offset, varies with the complexity of the timing between the reference and input signals.
Integer multiples of reference rates. If you are timing input signals with rates that are integer multiples of the reference rates, the instrument can measure the timing deterministically and displays the relationship as one circle (offset) relative to
the cross-hair. (See Figure 23.)
Figure 23: Timing display of integer multiples of reference rates
Such cases include timing an NTSC input (multiplier of 1) or a 525 SDI input whose frame time is 33.36 ms (multiplier of 2), against an NTSC reference, which has a frame time of 66.73 ms.
WVR7200 Waveform Rasterizers User Manual 45
Display Information
Non-integer multiples of reference rates. If you time input rates that are not integer multiples of the reference rates, the instrument cannot measure the timing deterministically, so it displays the relationships as several circles. Each circle represents a possible timing offset measurement relative to the reference cross-hair. Display emphasis is given to the circle that times closest to zero offset
and the numerical readouts track this pair. (See Figure 24.)
Figure 24: Timing display of non-integer multiples of reference rates
Non-deterministic cases include timing of slow rate inputs against fast frame-rate references or when timing video against film rates.
Multiple relationships. For a case where multiple relationships would display, consider an input of 1080p/23.98 Hz with a reference of NTSC/59.94 Hz:
The different rates result in timing relationships between the signals that repeat once for every four fields of the input and five frames of the reference.
Because this allows for five possible ways to measure timing between these two signals, the timing display shows four circles, with emphasis and readouts as previously described above.

Bowtie Display
Display Information
The Bowtie Display is accessed from the MEAS button. This display allows you to look at inter-channel timing between Y Pb and Y Pr. The left side of the display compares Y and Pb; the right side compares Y and Pr. The Bowtie
Display requires a test signal with signals of slightly differing frequencies on the chroma channels than on the luma channel.
If the bowtie patterns have a sharp null, and the null is at the center of each line, the relative amplitudes and inter channel timing are correct. Interchannel timing errors will move the position of the null. A relative amplitude error will decrease the depth of the null. An incomplete null combined with an offset from center indicates both amplitude and timing problems between the channels being

Eye Display
The Eye Display is accessible from the EYE button on the front panel of your instrument if it has Option PHY3. This display presents an eye pattern diagram of the SDI input, which lets you verify electrical characteristics of the SDI transport layer. Measure analog characteristics of the SDI input on the eye pattern using the graticule or voltage and time cursors.
Configure your instrument to show multiple Eye displays, each of which is controlled by one of two jitter engines: The Jitter1 engine controls Eye displays in the top two tiles and the Jitter2 engine controls Eye displays in the bottom two tiles. The two jitter engines allow you to set different filter bandwidths in the upper and lower tiles allowing you to monitor both timing and alignment jitter at the same time.
A jitter thermometer in the Eye display graphically relates the jitter measurement to alarm limits, and readouts display jitter magnitude. When displaying the Eye waveform in a single, full-screen tile, the measurement results and a histogram
display are included with the Eye waveform. (See Figure 31.)

Usage Notes
At the end of a long cable, the eye diagram may appear so noisy that there is little or no discernible opening. In this situation, limited use of the eye diagram is still possible by selecting Equalized Eye mode. The equalizer compensates for the effects of cable length by applying an inverse response function and then reslicing the signal to a logic level. This causes amplitude information to be lost, but preserves the effects of jitter in the signal.
If the equalized eye display appears clear with a substantial eye opening, then the signal is likely to be recovered error-free. However, if it appears noisy with little eye opening, then there is more potential for data errors to occur in the receiver.

Audio Control
The Audio Control Packet Display allows you to view information on audio frame number, sampling frequency, active channels, and relative audio-to-video delay of
each channel, as encoded in the audio control packet metadata. (See Figure 39.)
Figure 39: Audio Control Packet format
For SD signals, transmission of audio control packets is optional for 48 kHz synchronous operation and required for all other modes of operation (since it contains the information as to what mode is being used). Where frequent switching is planned, receiving equipment can be designed to add or drop a sample following a switch in the four out of five cases where the sequence is broken. The challenge in such a system is to detect that a switch has occurred.
This can be facilitated by use of the data block number in the ancillary data format structure and by including an optional frame counter with the unused bits in the
audio frame number word of the audio control packet. (See Figure 40.)
For HD signals, the audio control packet carries additional information used in the process of decoding the audio data and has a similar structure to standard definition.
The elements of the Audio Packet display vary depending on the monitored

Capture
Figure 49: Using cursors in the waveform display
There are two modes of capturing: Freeze and Buffer. The first mode can freeze a single tile, or all tiles simultaneously, and saves it to memory while other displays and information continue to be live. For this type of capture, frozen information is lost when the power cycles.
The second mode, buffer capture mode, captures and stores signal data for later recall to the instrument or to the USB drive for later analysis. The instrument can be set to buffer capture manually or using triggers. For procedures for copying the capture buffer to a USB drive, see the Technical Reference on the Product
Documentation CD shipped with your instrument. Both modes are useful for comparing sources or capturing transient events.
NOTE.
Both capture freeze and capture buffer information can be downloaded from the instrument Web page.
Capture freeze works in both four-tile and full-screen modes, however, if you freeze a trace in 4-tile mode, the image will not be shown if you go to full-screen mode. The image will still be available if you go back to 4-tile mode. Likewise, if you freeze a waveform image in a tile and then switch the tile to another measurement such as Vector, the frozen waveform image is hidden. If you then change the tile back to waveform, the image will reappear.
NOTE.
For waveform displays, the captured image is shown in a different color to distinguish it from the live image. For all displays, the instrument continues to log error status in the background while the display is captured.

Monitoring the SDI Physical Layer
With Option PHY3 installed, your instrument can use an eye pattern display, eye measurements, a jitter display, jitter detection and measurement, and an SDI status display to monitor and measure the SDI physical layer.
Display Types
Eye Display. This display allows you to use voltage and time measurement cursors and their readouts to monitor amplitude and timing measurements on an Eye waveform. You can configure your instrument to show multiple
Eye displays, each of which is controlled by one of two jitter engines: The
Jitter1 engine controls Eye displays in the top two tiles and the Jitter2 engine controls Eye displays in the bottom two tiles. The two jitter engines allow you to set different filter bandwidths in the upper and lower tiles so that you can monitor both timing and alignment jitter at the same time. There is also a jitter thermometer in the Eye display that graphically relates the jitter measurement to alarm limits, and there are readouts that display jitter magnitude.
When displaying the Eye waveform in a single, full-screen tile, the measurement results and a histogram display are included with the Eye waveform.
Jitter Display. With this display, you can view additional time-domain information that is useful in separating sources of jitter, whether they are within a single circuit on a circuit board, or from various pieces of equipment in a system. This includes jitter components that are synchronous or nearly synchronous to video line or video frame. These components appear as stationary or near-stationary artifacts in line or field sweeps and the wave shape of the jitter as modified by the high-pass filter setting.
(See page 57, Jitter Display.)
SDI Status Display. This display shows two measurements of signal jitter and cable loss in both dB and meters of the selected cable type, and calculated source level. Automatic measurements of eye amplitude, rise time, fall time, overshoot, and rise-fall difference are also displayed. Both the Jitter1 and
Jitter2 thermometers and the Cable Loss thermometer indicate signal loss due to cable length. With Option PHY3 installed, this display also shows the eye amplitude, eye risetime, eye falltime, eye risetime overshoot, eye falltime overshoot, and eye rise-fall delta measurement values.

To Make Eye Measurements
After you have configured the instrument for Eye measurements, you can have the instrument perform automatic eye measurements or you can use the cursors to perform manual waveform measurements. The following procedures explain how to conduct both measurement types.
NOTE.
If you use the measurement cursors to manually measure the eye waveform, you might get a different result than that shown in the automatic eye measurements readout. This is because the automatic amplitude measurement uses histograms to be minimally affected by overshoot, ringing, and noise on the signal. Similarly, the automatic rise time and fall time measurements use histograms to find the centers of the distributions of 20% and 80% crossings. The difference between manual and automatic measurements is usually insignificant for clean, symmetrical signals.
Eye Measurement Set Up
1. Configure your instrument to monitor the SDI physical layer. (See page 102.)

Measurement cursors on the Eye display
SDI Status display
Jitter display
NOTE.
Many jitter problems in systems have resulted from genlocking clocks to other references, such as the horizontal synchronization pulse. Reference jitter transferred by genlocks into a serial system is typically between 20 and several hundred Hertz. Also, the phase detection process used by the genlock can add noise, which results in jitter in the 10 Hz to 1 kHz range. Use the appropriate BW
Limit filter selection to include or reject genlock jitter from a measurement.
The simplest way to measure jitter is to use the jitter readout and jitter thermometer in the Eye display or SDI Status display. These are derived from the jitter waveform. For more qualitative jitter information, use the Eye and
Jitter displays to view the presence and magnitude of jitter and its potential for causing data errors as the eye closes. The Jitter display provides further analysis information including added time-domain information such as the wave shape of the jitter and whether there are jitter components that are synchronous or nearly synchronous to the video line or frame (these components appear as stationary or near-stationary artifacts in line or field sweeps).
Looking at jitter in both displays can help you separate jitter sources to determine whether they are within a single circuit on a circuit board or from various pieces of equipment in a system. If you are planning a composite D/A conversion, select the 10 Hz bandwidth filter to measure total broadband jitter.
jitter above 10 Hz is displayed. In the lower two tiles, the high-pass filter is set for 100 Hz, removing most of the 30 Hz jitter and leaving the spikes. Both Jitter displays are set for two-field sweep. The upper Eye display shows a fairly even jitter spread, which suggests a moderately uniform statistical distribution of jitter.
This jitter is from a sine wave component. Notice that there is no indication of jitter spikes. In the lower Eye display, the jitter is of a low-density haze, which suggests a less uniform jitter distribution. This is indicated by the spikes.

To Manually Measure Jitter
NOTE.
If you use the measurement cursors to measure jitter, you may get a different result than that shown in the jitter thermometer for the following reasons:
The internal peak detector does a better job of measuring jitter excursions than manually positioning the cursor; or The noise floor is removed from the jitter measurement readout but not from the cursor delta readout.
1. Perform the initial setup for Eye measurements. (See page 105, Eye
2. Use the SWEEP button to select the 3 EYE mode, which shows peak jitter at each eye crossing.
3. Use the Eye pop-up menu to set the jitter high-pass filter to one of the following:
To measure timing jitter, select the 10 Hz filter for both SD and HD signals, or select the Timing filter.
To measure alignment jitter, select the 1 kHz filter for SD signals or select the 100 kHz filter for HD signals, or select the Align filter.

Taking Cable Loss Measurements
After you have configured the instrument for Eye measurements, you can take cable loss measurements using the SDI Status display.
NOTE.
The accuracy of the Approx Cable (length) and Source Level readouts depends strongly on correctly setting the Cable Type and on the quality of the cable and connections in the signal path. These readouts are derived from the measured Cable Loss and the specified Cable Type. The Source Level readout of the SDI Status display indicates the calculated signal amplitude at the signal source, even when the signal level is greatly reduced at the instrument due to cable loss. Therefore, the automatic Eye Amplitude measurement (Option PHY3 only) may be significantly less than the indicated Source Level.
1. Perform the initial setup for Eye measurements. (See page 105, Eye

Checking Chroma/Luma Delay (Lightning Display)
The Lightning display can be used for interchannel timing measurements. If the color-difference signal is not coincident with luma, the transitions between the color dots will deviate from the center mark of a delay scale.

Checking Gamut
Checking Gamut
Signals that are legal and valid in one signal representation may not be legal in another representation. Specifically, signals which are legal in the Digital YCbCr representation may not be legal if transcoded to RGB or encoded to NTSC / PAL.
Any signal that fails this test is considered out of gamut.
Adjust Gamut Thresholds from the Configuration menu. From this same menu, you can also reset some gamut thresholds to default values.
Your instrument supports multiple displays and alarms to detect out-of-gamut signals. The flexible, tiled display allows you to simultaneously view several gamut measurements to learn which is most appropriate for a given application.
The displays are and their uses follow:
Diamond for checking that SDI signals conform to legal RGB gamut space
Split Diamond separates the upper and lower diamonds to show excursions below black; otherwise it is identical to the Diamond display
Arrowhead for checking if an SDI signal is legal for composite color space
Composite Waveform modes for checking both SDI and composite signals for legality in composite color space
Spearhead for showing lightness, color value, and saturation of the RGB color space
Diamond, Split Diamond, Arrowhead, and Spearhead have adjustable thresholds.
If the signal goes outside the area defined by the thresholds, the signal is out of gamut. If these limits are exceeded, then the instrument can generate alarms if configured to do so. For composite waveforms, the legal limit is simply the maximum level allowed for the combination of luma and chroma. This limit depends on the application. For example, a video tape machine may be able to record and play out signals with higher luma and chroma components than a transmitter.
To Set Up Gamut Checks
1. Connect a video signal to an input on the rear panel. Make sure to terminate it properly if it requires termination.
2. Select a tile in which to view the Gamut Display and press and hold the
GAMUT button.
3. In the Gamut pop-up menu, select of the following gamut display types:
Diamond – Use to detect, isolate, and correct RGB component gamut
errors. (See page 120, Checking RGB Gamut.)
Split Diamond – Use to reveal hard-to-find black gamut errors.
WVR7200 Waveform Rasterizers User Manual 119
Checking Gamut
Arrowhead – Use to detect composite gamut errors, without employing a composite encoder.
Spearhead – Use to detect RGB gamut errors.
4. Press the GAMUT button to dismiss the pop-up menu.
5. Press the CONFIG button and select Gamut Thresholds.
6. Set the thresholds as desired.
Checking RGB Gamut
The Diamond and Spearhead displays effectively show how the R, G, and B signals relate. The Diamond display is good tool for detecting gamut errors.
Spearhead requires Option PROD.
To form the Diamond display, the instrument converts the Y, P b, and P r components recovered from the serial signal to R, G, and B. To predictably display all three components, they must lie between peak white, 700 mV, and black, 0 V.
For a signal to be in gamut, all signal vectors must lie within the G-B and G-R diamonds. Conversely, if a signal vector extends outside the diamond, it is out of gamut. The direction of an excursion out of gamut indicates which signal is excessive. Errors in green amplitude affect both diamonds equally, while blue amplitude errors affect only the top diamond and red errors affect only the bottom

WVR7200 Waveform Rasterizers User Manual
Checking Gamut
Set the thresholds for gamut. (See page 119, To Set Up Gamut Checks.) After
selecting the Diamond display, compare the signal to the display to determine out-of-gamut components. Note the following:
The intensity of a vector indicates its duration.
A momentary out-of-gamut condition appears as a faint trace. Long duration violations show as a bright trace.
When evaluating out-of-gamut components, consider the following examples.
Example A:
R - Ok
G > 700 mV
B - Ok
Example B:
R - Ok
G - Ok
B > 700 mV
Example C:
R - Ok
G - Ok, 350 mV
B < 0 mV
Figure 60: Out-of-gamut examples
Usage Notes
As with the lightning display, bending of the transitions indicates timing delays.
When a color bar signal is applied, the vertical axis becomes an indicator of delay errors.
WVR7200 Waveform Rasterizers User Manual 121
Checking Gamut
On the Diamond display, monochrome signals appear as vertical lines. Nonlinear component processing, such as from a gamma corrector that alters white balance, can cause deviations along the vertical axis.
To isolate gamut bright-ups, try the following:
Use the LINE SEL button to select individual lines
Use the PICT display to examine the signal (turn on gamut bright-ups in the
Display Settings submenu of the Configuration menu)
Use the Diamond Area or Arrowhead Area settings (found in the Gamut
Thresholds submenu of the Configuration menu) to specify a percentage of the image pixels to ignore for gamut violations. The Gamut bright-ups, however, will continue to indicate all Gamut violations.
Checking Composite Gamut
The Arrowhead gamut display plots luminance (Y) against chrominance (C) to check if the composite signal adheres to standard gamut. NTSC and PAL
Arrowhead displays (75% Color bars) and indicates the values of the graticule lines. The arrowhead shape of the graticule results from overlaying the standard
limits for luminance and luminance-plus-peak chrominance. (See Figure 61.)
Figure 61: Arrowhead gamut display plots
122 WVR7200 Waveform Rasterizers User Manual
Checking Gamut
Set the thresholds for gamut. (See page 119, To Set Up Gamut Checks.) After
selecting the Arrowhead display, compare the signal to the display to determine out-of-gamut composite components. Note the following:
Signals exceeding the luminance amplitude gamut extend above the top horizontal limit (top electronic graticule line).
Signals exceeding the luminance plus peak chrominance amplitude gamut extend beyond the upper and lower diagonal limits.
The bottom horizontal line shows the minimum allowed luminance level. 0 or
7.5 IRE for NTSC and 0 mV for PAL.
Usage Notes
To automate this check, do the procedure Automating Gamut Checks. (See page 123.)
Checking Luma Gamut
Luma limit thresholds can be configured for identifying luma exceeding threshold limits. They apply to both the incoming SDI and to the Arrowhead representation of the SDI input as a composite signal. By defining these levels in percent, they automatically account for the presence or absence of setup. The thresholds are affected by your choice of set-up or no set-up for the Arrowhead display.
Set the thresholds for gamut. (See page 119, To Set Up Gamut Checks.) After
selecting the Arrowhead display, compare the signal to the display to determine out-of-gamut luminance. Note the following:
The adjustable thresholds are indicated by the dark blue horizontal graticule lines.
The thresholds are defined in terms of percent of full scale.
The range for the Upper limit is 90% to 108%.
The range to the Lower Limit is -6% to +5%.
Another useful Arrowhead function is a measure of how well the active video signal is using the dynamic range of the video channel. A properly adjusted signal should be centered in the arrowhead graticule and have transitions that approach all the limits.
Automating Gamut Checks
You can use alarms to automatically monitor for out-of-gamut conditions.

The Audio Surround Sound display is courtesy of Radio-Technische
Werkstaetten GmbH & Co. KG (RTW) of Cologne, Germany.
The Level Indicators – indicates the audio level balance among the left (L), right (R), left-surround (Ls), and right-surround (Rs) channels as cyan lines on the Loudness Grid.
The Loudness Grid – the ruled scale, radiating from the center, on which the level indicators register their audio level and balance. The scale has tic marks at 10 dB intervals. An additional tic mark indicates the -18 dB level. The
-18 dB and -20 dB levels are typically used for aligning audio levels.
Total Volume Indicator – the cyan polygon formed by connecting the level indicator end points, showing the total sound volume of the L, R, Ls, and
Rs channels. Each connecting line bends away from the center if the two signals have a positive correlation, bends toward the center if the signals have a negative correlation, and do not bend if the signals are uncorrelated.
The Center Volume indicator – displays the sound volume of the center channel as a vertical yellow bar between the L and R channels, and connects the ends of the L, C, and R audio level indicators with straight lines.
Channel-Pair Phantom Sound Indicators (PSIs) – located on each side of the
Surround Sound display, indicates the location of potential phantom sound sources formed by adjacent channels. The white tic marks on these moving bar indicators show the phantom source locations. The bar length indicates
146 WVR7200 Waveform Rasterizers User Manual
Audio Monitoring the correlation between the adjacent channels. A short-to-medium length green bar indicates positive correlation between the channels, forming a localized phantom sound source located at the white tic mark. The bar grows to full length and changes color to yellow as the correlation moves to zero, indicating a wide, non-localized sound image. The bar changes color to red for adjacent channels with significant negative correlation. For negative correlations, the ends of the PSI for the L and R channels continue to grow at a 45° angle while the other PSIs remain at full length.
Center-Pairs Phantom Sound Indicator – a fifth PSI at the top of the display shows potential phantom sources formed by the LC channel pair and the CR channel pair. If the L, R, and C channels all have the same signal level, the white tic mark on the bar appears directly above the C level indicator. The white tic mark moves right or left depending on the relative balance between the three channels. A short bar to the left of the white tic mark indicates a positive correlation between L and C. The bar grows as the correlation decreases. Like the L-R PSI, the bar continues to grow at a 45° angle for negative signal correlations. The bar to the right of the white tic mark behaves similarly, depending on the C-R correlation. This PSI indicator uses the same color coding as the other PSI indicators.

Usage Notes
The displays shown here are examples of how the surround sound waveform appears for some typical signal types.
1. Uncorrelated signals: same level in the L, C, R,
Ls, and Rs channels.
2. Sine wave test tone: same level in the L,C, R,
Ls, and Rs channels. All signals are in phase, creating phantom sources between the adjacent channels.
3. Same as 2, with the exception that Channel L is out of phase.
4. Surround sound program with strong center channel presence.
5. Surround sound program with weak center channel presence.
6. Monaural signal in channels Ls and Rs, creating a phantom source in the center, as in a 3.1 surround sound system.

NOTE.
If you select VANC at the metadata source, select the VANC source, as well.
Usage Notes
Your instrument determines the downmix based on several parameters within the Dolby metadata and the Dolby downmix selection. For example, if the
Dolby Audio Status screen shows Extended Bitstream information indicating that the preferred downmix is Lt/Rt, the center channel is attenuated by -3 dB and the surround channels are attenuated by -6 dB before they are combined into the stereo downmix.
The listening modes can be used to monitor any multichannel Dolby Digital audio program with a user-selectable number of channels. You can select among several basic and Pro Logic listening modes, the descriptions of which follow. Depending on the Channel Mode, these listening modes affect the
content displayed on the Audio Display level bars. (See Table 6 on page 156.)
Basic Listening Modes
EX. Use EX if the two surround channels have been matrix encoded with a back channel. If the EX listening mode is selected and there are two surround
WVR7200 Waveform Rasterizers User Manual
Audio Monitoring channels present, the bar display adds two back channels, Lb and Rb, to create a 7.1 channel display.
Full. Full does not modify the number of channels indicated by the channel mode in either the display or the outputs.
3 Stereo. Use 3 Stereo to monitor the Dolby Digital signal with only the left, center, and right channels. In this mode, if there are surround channels present, they are mixed into the left and right channels with the surround mix level attenuation.
Phantom. When using Phantom, the center channel, if present, gets attenuated with the center mix level value and is then added into the left and right channels.
Stereo. Stereo always creates a Lo/Ro downmix using the center and surround mix levels contained in the metadata. The Lfe is disabled.
Mono. Mono mode will always mix down to a single center channel, usually by creating a Lo/Ro downmix and adding Lo to Ro. The Lfe is disabled.
Pro Logic Listening Modes
Pro Logic listening modes perform different functions depending on what the source material is. If the source is a Dolby Digital stream with three or more channels, then a surround compatible Lt/Rt downmix is created and then decoded into a selectable number of channels. If the source is a 2/0 Dolby Digital stream, then these Pro Logic modes will do a Pro Logic decode to produce the number of channels requested by the listening mode. If the source is PCM, then a full Pro
Logic decode is provided regardless of the specific Pro Logic mode selected.
Pro Logic Full. Pro Logic Full creates a Lt/Rt downmix of any input with three or more channels. This Lt/Rt downmix will then be Pro Logic decoded to produce a LCRS output where the surround channel is reduced 3 dB and reproduced in both the Ls and Rs bars.
A 2/0 encoded Dolby stream is assumed to be Pro Logic encoded already and is
Pro Logic decoded to produce a LCRS output. Again, the surround channel is reduced 3 dB and reproduced in both the Ls and Rs bars.
Any PCM input is decoded the same as a 2/0 Dolby Digital input.
Pro Logic 3 Stereo. Pro Logic 3 Stereo creates a Lt/Rt downmix of any input with three or more channels. This Lt/Rt downmix will then use Pro Logic decoding to produce a center channel and provide LCR bars.
A 2/0 encoded Dolby stream is assumed to be Pro Logic encoded already and is
Pro Logic decoded to produce a LCR output.
Any PCM input is decoded to provide LCRS channels where the surround channel is reduced 3 dB and reproduced in both the Ls and Rs bars.
WVR7200 Waveform Rasterizers User Manual 155

Pro Logic Phantom. Pro Logic Phantom creates a Lt/Rt downmix of any input with three or more channels. This Lt/Rt downmix will then use Pro Logic decoding to produce a surround channel and provide LCS surround channels. This surround channel is reduced 3 dB and reproduced in both the Ls and Rs bars.
A 2/0 encoded Dolby stream is assumed to be Pro Logic encoded already and is
Pro Logic decoded to produce a LRS output. Again, the surround channel is reduced 3 dB and reproduced in both the Ls and Rs bars.

Timing a Studio
Your instrument supports multiple methods and techniques for timing a studio, all of which require an external reference to your instrument. Timing a studio involves adjusting the references going to different sources so that their output feeds have the same timing when they arrive at a common point, such as a production switcher. For digital systems, timing typically must be close, but not exact, because most switchers have some tolerance for timing errors. For analog composite systems, the timing may need to be matched within a small part of a subcarrier cycle to prevent hue shifts when switching between sources.
Following are procedures for timing a studio using various methods.
Using the Traditional
Method
Your instrument makes the traditional method of comparing Horizontal and
Vertical timing easier by providing flexible tiles and a Freeze function. To time a studio using the traditional method, you store an input as a baseline and compare signals that you time against the baseline.
1. Select a tile in which to time the active input. Select WFM.
2. Apply the first input signal to the appropriate input, terminate it properly, and select it.
3. Push and hold the WFM button. From the Display Mode submenu, select a display mode that is appropriate to the signal that you input.
4. Apply the house reference signal to the external reference input, terminating it properly.
5. Press the EXT REF button to select External Reference mode. (Connected to the house reference.)
6. Put the selected tile in line mode.
7. Use the HORIZONTAL knob to center the sync edge or the SAV pulse. (If using the SAV pulse, turn off Stripping EAV/SAV/ANC in the SDI Input setting of the Configuration Menu.)
8. Press the MAG button to increase the timing resolution.
9. Select a second tile.
10. Press the FIELD button to put a second tile in field mode and choose an appropriate waveform mode.
11. Use the HORIZONTAL knob to center the vertical interval.
12. Press the MAG button to increase the timing resolution.
13. Press the CAPTURE button to save the waveform as a baseline.
WVR7200 Waveform Rasterizers User Manual 165
Application Example
14. Apply an input that matches timing of the first input.
15. Adjust the timing offset of the signal being timed to match the timing to the saved baseline.
16. Repeat steps 14 and 15 for any other required signals.
NOTE.
Use the Cursors as markers or to measure timing differences between sources.
Other tiles can be used to set fine timing and check color frame alignment on composite signals. Alternatively, the other two tiles could be used for line and field rate displays without Mag active to show the location of significantly mistimed signals.
Using the Timing-Display
Method
The Tektronix Timing Display provides a quick, easy way to measure the timing of an input relative to the external reference:
The rectangular display automatically scales to match the input signal. For progressive signals, the display represents one field; for interlace signals, the display represents one frame; and for composite inputs, the display represents one color frame.
The cross-hair in the center represents zero offset, and the circle represents the timing of the input signal. Lines of advance or delay are shown as vertical displacement, while timing errors of less than one line are shown as horizontal displacement. If the input is at the same time as the reference, then the circle is centered on the cross-hair.
The timing offset is also shown numerically as lines and micro-seconds of advance or delay in the boxes at the right side of the display.
For input and reference signals with closely related frame rates, there is only one timing relationship, so a single circle is shown on the display to indicate the timing offset of the input signal.
For input and reference combinations with more complex relationships, multiple circles are displayed to indicate all the possible interpretations of the timing offset, with the one that is closest to zero shown with emphasis.
The numerical readouts will correspond to the timing indicator circle with the emphasis.
The Relative to: box indicates the chosen zero point for the timing display.
The default is Rear Panel. In this mode, the offset is zero when the input and reference are at the same timing at the rear panel of your instrument. The other choice is Saved Offset. In this mode, you can save the timing from one signal and then display the timing relative to that saved offset.
166 WVR7200 Waveform Rasterizers User Manual
Application Example
To Use the Timing Display to Time a Signal to a Reference.
1. Select a tile in which to time the active input.
2. Apply the input signal to be timed to the appropriate input, terminate it properly and select it.
3. Apply the house reference signal to the external reference input, terminating it properly.
4. Press the EXT REF button to select External Reference mode.
5. Press the MEAS button to select the Timing display for the tile selected in
6. If only one circle is displayed, adjust the timing offset of the black generator to match the timing to the external reference. Adjust for a perfect coincidence of the circle around the reference target (circle turns green at coincidence) and null values of the vertical and horizontal timing readouts.
7. If multiple circles are displayed, the timing is complex, and you must choose the one you want. The measurement that is closest to zero offset is displayed with emphasis and appears in the readouts.
NOTE.
See Timing Displays for Simple Versus Complex Timing for more
information about complex timing displays and their elements. (See page 45.)
Usage Notes
9. Repeat step 6 or 7 for any other signals.
NOTE.
As you adjust timing, the circle representing the input timing may jump occasionally. This is because the color frame detection circuit can be temporarily disrupted as the signal shifts. The jump is often a multiple of the field time. The circle will settle back to the correct location in a second or so.
The resolution of the timing display for Composite and SD signals is one
27 MHz clock cycle or 37 ns. For HD signals, it is one clock at 74.25 MHz, which equates to about 13.5 ns. To get the greater accuracy needed for a composite signal, first use the timing display to get close, then use a vector display for the final burst phase alignment. Since this instrument can display both the timing display and a vector display simultaneously (each in its own tile), this process can still be easy and quick.
For composite signals the definition of time aligned is obvious but for an
SDI input relative to a analog reference the situation is more complex. For the timing display, the definition of zero offset on an SDI input uses the methodology described in SMPTE RP168. This method specifies the SDI signal is converted to analog. The converted analog signal is then compared
WVR7200 Waveform Rasterizers User Manual 167
Application Example to the analog reference. For the conversion, a D/A converter with delay of about three microseconds is used.
In the Relative to Rear Panel mode, this three microsecond conversion delay is accounted for in the displayed offset. In the Relative to Saved Offset mode, it has no effect.
Timing Multiple Inputs to a
Router
Use the Relative to: function to set the offset between a master signal and a reference signal as the zero-point reference for time-down applications. The
Relative to: box indicates the chosen zero point for the timing display:
Rear Panel. In this mode (default), the offset is zero when the measured signal input and reference are at the same timing at the reference at the instrument rear panel. This setting was used in the Timing Display Method procedure.
Saved Offset. In this mode, you can save the timing from a master signal relative to the reference as the zero point offset. Then route other inputs and measure relative to this saved offset.
To Time the Inputs to a Router.
1. Perform steps 1 through 5 of the previous procedure.
2. Route the signal you want as the master to the appropriate input, SDI or
Composite, and terminate properly.
3. Route the reference signal to the reference input and terminate appropriately.
4. Save the timing offset for the master input (MEAS > Save Offset > SEL) and select the Relative to: Saved Offset mode from the pop-up menu.
NOTE.
You cannot save the timing offset if either the input or reference is missing or unlocked. You also cannot save a reference when in internal mode. Saving an offset in these conditions would lead to misleading results so it is not allowed by the instrument. A warning message will appear on the screen if you attempt to save the offset when it is not allowed.
5. Now select other inputs to the router to be connected to the instrument. For each input, the relative timing is displayed.
6. Adjust the timing offset at the master sync source to time down the inputs to the router to match the master.
168 WVR7200 Waveform Rasterizers User Manual
Application Example
Usage Notes.
The resolution of the timing display is one 27 MHz clock cycle or 37 ns, for
Composite and SD video. To get the greater accuracy needed for a composite signal, first use the timing display to get close, and then use a vector display for the final burst phase alignment. Since these two displays can be present simultaneously in separate tiles, this process is still easy and quick.
For composite signals, the definition of time aligned is straight forward, but for an SDI input relative to an analog reference, the situation is more complex.
For the timing display, the definition of zero offset on an SDI input assumes the SDI signal is converted to composite. The converted composite signal is then compared to the analog reference. For the conversion, a half-band filter with a 33 clock-cycle delay and an analog reconstruction filter are assumed.
This conversion introduces a delay of about 3 µs.
In the Relative to: Rear Panel mode, this 3 µs conversion delay is removed from the measured offset before the display is generated. In the Relative to:
Saved Offset mode, it has no effect.
This timing relationship between input and reference is also compatible with the waveform mode. That is, if you have zero timing on the Timing display and change from internal to external reference, the displayed waveform will not shift position.
When timing analog composite signals, adjust the system phase with the
Vector display. (See page 45, Timing Displays for Simple Versus Complex
NOTE.
If you have an input and reference combination that requires multiple timing indicator circles, then it can be misleading to compare timing offsets between multiple inputs. Because the timing display chooses the smallest of the possible timing offsets, if a large timing difference exists between two inputs, then they may not be matched. This problem also occurs using traditional timing methods unless you use something similar to the SMPTE318 10 field flag to identify a specific sub-multiple of the reference.
